The EU publishes its first AI Act harmonised standard

The European Commission has published the reference to the first harmonised standard supporting the AI Act in the Official Journal of the European Union. The standard is EN 18286:2026, titled Artificial intelligence: quality management system for EU AI Act regulatory purposes, developed by the European standards bodies CEN and CENELEC.

It gives providers of high-risk AI systems a clear way to meet the quality management requirements in Article 17 of the AI Act. Providers that implement it get a presumption of conformity with those requirements. Using the standard is voluntary, and it is not tied to one sector.

The decision citing the standard was adopted on October 12 and entered into force on October 14, when it appeared in the Official Journal. The Commission's own announcement followed on October 19.

High-risk AI requirements apply from December 2027 and August 2028, and more harmonised standards are expected. This first standard covers quality management only.

Our take

Quiet, but it is the first piece of the AI Act's rulebook that companies can follow to the letter. Standards are how law becomes a checklist.
